: I am finishing a bathroom in my basement and code required an exhaust fan. What are my options as to where to put the vent? Can I vent it into the other part of the basement or possibly into the drain waste venting system? It would be very difficult to vent to the oustside.

Greg, Do not vent to the existing plumbing vent!!! You are going to have to vent this to the outside. Sorry. Dale Peck LMP
